Solve for c. 2/5c + 5 = 95

Answer 1

To solve for c, we can first subtract 5 from both sides of the equation:

2/5c + 5 - 5 = 95 - 5

2/5c = 90

Next, we can multiply both sides of the equation by the reciprocal of 2/5, which is 5/2:

(2/5c) * (5/2) = 90 * (5/2)

c = (90 * 5) / 2
c = 450 / 2
c = 225

Answer 2

What value for n makes this equation true?
13- 2n = - 109

Answer 3

To find the value for n that makes the equation 13- 2n = - 109 true, we can solve for n by isolating it on one side of the equation. Here's how:

Step 1: Subtract 13 from both sides of the equation:
13 - 2n - 13 = -109 - 13

This simplifies to:
-2n = -122

Step 2: Divide both sides of the equation by -2 to solve for n:
(-2n) / -2 = (-122) / -2

This simplifies to:
n = 61

Therefore, the value for n that makes the equation true is n = 61.

Answer 4

Three hundred students went on a field trip to the zoo. Six buses were filled and 12 students rode in cars. How many students were on each bus?(1 point)

Answer 5

To find out how many students were on each bus, we can subtract the students who rode in cars from the total number of students, and then divide that by the number of buses.

Total number of students = 300 - 12 = 288

Number of students on each bus = 288 / 6 = 48

Therefore, there were 48 students on each bus.

Answer 6

Clara wants to bike 112 miles this week. That is 20 miles less than 2 times the number of miles she biked last week. How many miles did she bike last week?(1 point)

Answer 7

Let's assume the number of miles Clara biked last week is x.

According to the problem, Clara wants to bike 112 miles this week, which is 20 miles less than 2 times the number of miles she biked last week.

So we can write the equation as:
2x - 20 = 112

Now, let's solve the equation for x.

Add 20 to both sides of the equation:
2x - 20 + 20 = 112 + 20
2x = 132

Divide both sides of the equation by 2:
2x/2 = 132/2
x = 66

Therefore, Clara biked 66 miles last week.
